100.

Without knowing how PHP seeds the generator it is difficult to predict

1. change the number to a string: $t = (string) time();
2. chop off the last char of the string: $char = substr($t, -1);
3. you're done...: include footer$char.html;
Time wins certainly produces better results, at least for what I am
doing, than rand...
Thanks all for your input...

Get the time and use the last digit converting 0 to 10.
Here's how you generate a random number:

There are a number of things you can do with that to select a random file and
include it. Have an associative array where the random number matches an

Use a database query to verify the random number has not been used before.
$number_checker = 1;
while ($number_checker != 0){
#insert your $random_number code
$query = SELECT COUNT(*) AS total FROM some_table WHERE
random_number_field = '$random_number';

Many thanks Thomas and Maciek. I'll try removing mt_srand to start with,
and if that doesn't work out I'll put in the uniqueness check.

Hi shaun,
Store all those numbers in an array and use the function
array_rand.

It's no good just telling us it doesn't work. You need to tell us what
happens when you run it.
Use this function, the $num argument, is the total
of numbers. Ex: if $num is 5, the funtion will return
56743, is five numbers.
function random($num)
{
srand ((double) microtime() * 100);

$temp = substr($temp, 0, $num);

If you need just plain random number generator check manual. If you want a
true pseudo-random number generator you may want to check:
http://www.ulib.org/webRoot/Books/Numerical_Recipes/bookcpdf.html
Those generators used in scientific calculations where true reproducible and
low correlated
why not use the rand() ?
manual says:
rand -- Generate a random value
Description
int rand ([int min [, int max]])
If called without the optional min, max arguments rand() returns a
pseudo-random value between 0 and RAND_MAX. If you want a random number
between 5 and 15 (inclusive), for

Try this:
mt_srand((double)microtime()*100);
